Fuel System Primary Filter/
Water Separator - Drain
Fuel leaked or spilled onto hot surfaces or electri-
cal components can cause a fire. To help prevent
possible injury, turn the start switch off when
changing fuel filters or water separator elements.
Clean up fuel spills immediately.
NOTICE
Ensure that the engine is stopped before any servic-
ing or repair is performed.
NOTICE
The water separator can be under suction during nor-
mal engine operation. Ensure that the drain valve is
tightened securely to help prevent air from entering
the fuel system.
Drain Procedure
1. Place a suitable container under the water
separator to catch any fluid that might spill. Clean
up any spilled fluid.
2. Ensure that the outer body of the filter assembly is
clean and free from dirt.
